Abstract
The utility model relates to an automatic frequency conversion boiler straw raw material feeder and belongs to the technical field of boiler feeding equipment. The automatic frequency conversion boiler straw raw material feeder is composed of a hopper, a packing auger, a packing auger motor, a frequency converter, a union pipe, a draught fan, a fuel atomizing pipe and the like. One end of the packing auger is provided with the hopper and is connected with a gearbox and the packing auger motor which is provided with the frequency converter through chains. The other end of the packing auger is provided with an air intake feed pipe and the union pipe which is provided with the draught fan. The upper portion of the draught fan is provided with the fuel atomizing pipe. The automatic frequency conversion boiler straw raw material feeder utilizes the packing auger and wind power to feed, controls feeding speed through an air and material adjusting valve and the frequency converter and is controllable in firepower size. In a process of feeding in a spraying mode, the automatic frequency conversion boiler straw raw material feeder conducts second air intake on a boiler, increases oxygen quantity of a furnace, enables the combustion to be abundant and saves combustion cost by 5 to 10 percent compared with feeding through manual work. The automatic frequency conversion boiler straw raw material feeder is low in the pollution of the environment and low in labor intensity of workers, thoroughly solves the problems that labor intensity of feeding through manual work is high, the feeding is not even and consumption is not abundant and is suitable for using in various vertical type or horizontal type boilers.
Description
Technical field
The utility model relates to a kind of boiler stalk feeder of automatic frequency-conversion, belongs to boiler feeding apparatus technical field.
Background technology
Traditional vertical or horizontal boiler all is to act as a fuel with coal, but, coal is a kind of have maximum discharge, high pollution, expensive and non-renewable fuel, along with the minimizing of coal resources and people to the attention of environmental protection, adopt the fuel of cleaning, environmental protection can replace coal to become a kind of trend.Adopt at present straw to replace coal fuel to obtain people's approval, straw has the characteristics of high heating value, low ash content, low emission, low cost, low labour intensity, and remaining ash content is rich in potassium after the burning, is the necessary organic fertilizer of crops.On the other hand, solved also that the peasant burns maximum discharge that straw brings and to the pollution problem of atmosphere.Although adopt straw to replace coal to have above-mentioned many benefits as fuel the very trouble because straw feeds intake as boiler oil the time, cause straw fuel use and to promote resistance very large, most of straw or burned or slattern.
Summary of the invention
The purpose of this utility model is, provide a kind of and adopt auger and wind-force to feed intake to straw fuel, and by gas material control valve and variable-frequency motor control rate of feeding, the firepower size control freely; Thoroughly solved straw as the boiler oil trouble that feeds intake, the labor strength that feeds intake, the boiler stalk feeder of the automatic frequency-conversion of the insufficient problem of fuel combustion.
The utility model is to realize by the following technical solutions above-mentioned purpose:
The boiler stalk feeder of this automatic frequency-conversion is made of hopper, air intake feed pipe, auger, auger motor, gearbox, frequency converter, connecting tube a, connecting tube b, blower fan, gas material control valve, blower motor and fuel injection pipe, it is characterized in that: above the end of auger hopper is housed, the end that hopper is housed of auger is connected with a gearbox and auger motor by chain, and the auger motor is connected with a frequency converter by wire; The other end of auger is equipped with the air intake feed pipe, and the air intake feed pipe is equipped with gas material control valve by the air inlet of connecting tube a connecting fan on the air inlet of blower fan; One side of blower fan is equipped with blower motor, is connected with fuel injection pipe by connecting tube b on the air outlet on blower fan top, and the fiery sealing ring of gear and boiler door hanging are housed on the fuel injection pipe, and fuel injection pipe is fixed on the bracing frame.
The utility model beneficial effect compared with prior art is:
The boiler stalk feeder of this automatic frequency-conversion adopts auger and wind-force to feed intake, and by gas material control valve and variable-frequency motor control rate of feeding, the firepower size is controlled, has greatly alleviated kettleman's labour intensity.And in the process that wind-force feeds intake, play the effect of secondary air to the burner hearth of boiler, increased the amount of oxygen of burner hearth, so that the discharging flue gas after the burning meets discharging standards, reduced the pollution to environment, than Manual material feeding saving burning cost 5～10%.It is large that the boiler stalk feeder of this automatic frequency-conversion has thoroughly changed artificial delivery of past fuel labour intensity, the firepower size is uncontrollable, stalk drops into inhomogeneous, insufficient waste of fuel that causes of burning, cause straw fuel use and to promote resistance large, most of straw or the problem of being burned or slatterning are applicable to various vertical or horizontal boiler uses.
Description of drawings
